It contains all the levels, tile sets and music from Holiday Hare '98, but adds Lori Jackrabbit as a new playable character, the sister of Jazz and Spaz. Lori debuted in The Secret Files. It also includes JCS (Jazz Creation Station), the official Jazz Jackrabbit 2 level editor. It supports local and online multiplayer games. Due to the publisher's bankruptcy, it was originally only released in Poland and later in small quantities in other European countries.
